Jinling.

The entrance to the experimental building of the Clinical Medicine Center in the Hexi Campus of the First Hospital.

Xu Xiaohe, the director of the Hexi Branch of the First Hospital, was standing at the entrance of the stairs waiting. After a while, a Hongqi car drove up from a distant intersection.

Seeing this familiar car, Xu Xiao's eyes lit up and he walked over quickly.

"Brother!"

The cart opened the door and as soon as Xu Chuan stepped out, a familiar voice sounded in his ears.

With a smile on his face, he looked over and saw Xu Xiao, who was wearing a medical white coat with a ponytail swaying. He hadn't seen him for more than a month, and his face had lost a lot of weight, with some dark circles under his eyes.

"You've lost a little weight. Have you stayed up late recently?" Xu Chuan asked with a smile as he looked at his younger sister.

Xu Xiao: "It's hard not to endure it. If brain-computer interface technology is solved sooner, those with disabilities will be able to resume their normal lives one day earlier."

Xu Chuan smiled, and just as he was about to joke, another voice came to his ears.

"Academician Xu, welcome, welcome to the First Hospital to guide research work."

Beside the cement steps, a middle-aged and elderly man walked up with a smile on his face and extended his hands enthusiastically.

On the side, Xu Xiao smiled and helped explain: "This is Director Cao Hongsheng of Jinling First Hospital. The cooperative clinical research between Starlight Brain-Computer Interface Technology and the First Hospital was promoted by Director Cao."

Xu Chuan smiled and stretched out his hand, shook hands with Dean Cao, and said, "Hello, Dean Cao, I'm sorry to trouble you with Xu Xiao's research."

With a smile on his face, Cao Hongsheng said quickly: "No trouble, no trouble, this is no trouble. It is a pure honor for our hospital to be able to cooperate in scientific and technological research in such a cutting-edge field. It is Xu Xiao who takes care of us."

"

After exchanging a few words at the door, Xu Chuan was not prepared to waste time. He looked at Xu Xiao and said, "I have already seen an overview of the experimental data on the way here. Now take me to see your clinical experimental research.

"

Xu Xiao nodded, turned around and led the way towards the building.

Taking the elevator, the group arrived at the seventh floor of the clinical research center building.

After passing through the corridor, we entered a room inside the research center that didn't look much different from a ward. Inside were two middle-aged men who voluntarily accepted the experiment.

Xu Chuan glanced at them and found that both of them were typical disabled people.

The difference is that one of them is missing his right leg, which is nearly half of his thigh, and even his knees are missing.

Another person was missing his left hand and had it amputated close to the elbow joint.

The same thing is that the two people who lost their limbs have already undergone surgery and been fitted with silver-white artificial prostheses.

However, perhaps because of the ongoing clinical trials, neither the right leg prosthesis nor the left hand prosthesis is covered with bionic skin, and the various components and pipelines on the robotic arm are clearly visible.

This is to facilitate various debugging work during the clinical trial process.

Seeing a group of people doing the experiment, in the room, among the two middle-aged men undergoing the experiment, the middle-aged man who was missing his left arm stood up and walked over.

"Expert, my arm always feels a little trembling and swollen when I control it. This kind of experiment really has no impact on the body, right?"

As he spoke, he touched the back of his head with his right hand. Although he couldn't touch it with his hands and usually didn't feel anything strange, there was an extra thing in his brain, which always made him feel very awkward.

After all, for a farmer like him, it's always unsettling to plant something that doesn't belong to you in a place like your brain that could kill you if you hit it wrongly.

Especially after the prosthetic limb was transplanted to his left hand, although he could control it, he still had twitching and shaking from time to time and made some movements that he had never thought of. But the prosthetic limb was made by himself, which made him a little flustered.

Xu Xiao walked over, rolled up the half sleeve on the other person's arm, carefully observed the interface between the implanted bionic prosthetic limb and the arm itself, pressed the skin, confirmed that there was nothing wrong, and comforted him with a smile.

"Don't worry, the anastomosis at the transplant site is recovering very well."

"We use the best bionic materials, which can be well integrated with the human skin and bones. At present, the bionic skin and materials have grown and healed together with your own arm tissue."

"As for some occasional twitching, shaking and other movements when using it, these are currently normal."

"After all, this new technology still needs to be continuously optimized. Don't worry, although there are still some minor problems in its use, I can guarantee that the transplanted bionic robotic arm and brain-computer chip will not have any other impact on your health.

.”

Xu Xiao patiently explained that she had actually said these words more than once or twice.

However, she still maintained a gentle and patient attitude towards the two patients participating in the clinical trial.

After explaining with a smile, Xu Xiao pulled Xu Chuan out from behind, pushed him in front of the patient undergoing clinical experiments, and said with a smile.

"If you don't believe me, then you should know him. Academician Xu Chuan, who often appeared on TV before."

After looking at Xu Chuan, the middle-aged farmer was full of excitement and said with a grin: "I know the great scientist. I saw it on TV before. He said that he discovered some fusion technology and now the electricity bill has been reduced."

Once I get it, my family can save more than a thousand yuan a year."

Xu Xiao smiled and said: "He came here this time specifically to deal with problems with the bionic robotic arm you transplanted."

"Don't worry. After a while, your arms and calves will become the same as your original arms and thighs. You can use them normally, live a normal life, and work normally."

Hearing this, the middle-aged man's face was full of smiles. He couldn't help nodding and laughing: "That's a good relationship, that's a good relationship. Sorry to bother you, experts. Thank you, great scientist."

Xu Chuan smiled and said hello to the middle-aged man undergoing clinical experiments with a smile. After pretending to help check the condition of the transplanted arm, he smiled and changed what Xu Xiao had said into a new set of words.

once.

On the side, Xu Xiao smiled and said: "You two, follow me, now go to the clinical trial center."

"This time Academician Xu is here to see the experimental conditions of these bionic robotic arms. We have to go through the experimental process normally according to the previous experimental process."

With that said, she took the lead and walked out of the room. Xu Chuan did not move for the moment, and his eyes fell on the two disabled men who were receiving and transmitting brain-computer interface bionics robotic arms clinical experiments.

Of course, the main focus fell on another experimenter who had lost his right leg, observing the walking condition of his prosthetic right leg.

Although it is said that because there is no bionic skin wrapped around it, this bionic mechanical leg looks a bit out of place.

But there is no big problem when walking.

Whether it is bending the knees, raising the legs, or landing the heels and then touching the bottom of the entire foot, these ordinary walking postures are almost perfectly achieved.

On the side, Zheng Hai squinted his eyes for a while and then said: "This comrade who lost his right leg should have come out of the army, and he should have been discharged not long ago."

Hearing this, Xu Chuan glanced at him in surprise and asked curiously: "How did you know?"

Zheng Hai smiled and said: "Temperament, and the way you walk."

"Although it looks a little different due to the mechanical leg installed on it, I can't mistake this feeling."

"A farmer and a soldier."

Xu Chuan smiled and said, "The clinical experimenters she chose are quite interesting."

Zheng Hai was noncommittal and asked: "This kind of mechanical leg shouldn't be cheap, right?"

Xu Chuan: "The cost should exceed one million. This is clinical experimental equipment with the most detailed functions."

After Musk bought back the Neuralink brain-computer interface company, it merged with the 'Starlight Virtual Technology Company' that he helped Xu Xiao open before.

Although the specific cost of this bionic robotic arm is not clear, it is definitely worth a lot of money.

Hearing the price, Zheng Hai frowned and said, "If that's the case, I'm afraid many people can't afford it."

Xu Chuan smiled, followed the leaving experimental team, and said: "Every new technology is expensive when it first appears."

"Just like mobile phones and computers, when they first appeared, not many people could afford them."

"But with the development of the times, isn't it true that almost everyone now has a mobile phone and a computer? Take your time, don't rush."

.....

The clinical laboratory is located on the other side of the seventh floor.

When Xu Chuan followed, Xu Xiao and related researchers were already making various preparations.

After waiting for a while, a scientific researcher in a white coat took Xu Xiao's place and walked over with a recording board in his hand.

"Today's experiment is the same as before. Which of you will come first?"

Hearing this, in the laboratory, another middle-aged man who had lost his right leg raised his hand and said, "I'll do it first."

Following the voice, Xu Chuan looked over.

This laboratory is quite large and contains various experimental equipment.

With the help of the staff, the soldier who came out of the army quickly put on various sensor data devices.

Walking, jogging, running fast, squatting, squatting on one leg, standing on one leg...sitting, lying, weight-bearing...quick response, flexibility...

A series of basic lower limb functional tests are being carried out in the laboratory.

Standing in the laboratory, Xu Chuan observed the activities of the clinical trial subject with great interest.

On the side, Xu Xiao spoke softly and explained: "For bionic manipulators, these basic tests can be mainly divided into motion range, speed performance, acceleration performance... position repeatability accuracy, path tracking accuracy, collision

Testing...Load performance testing and other seventeen categories."

"Beyond that, there are some other optional tests."

"For example, force control testing, modal analysis, disturbance suppression, environmental adaptation testing, battery life, etc."

"The combination of basic tests and optional tests can make a comprehensive evaluation of the control system, power supply system and other systems of the bionic robotic arm and brain-computer chip. Both overall performance and reliability can be completed in these tests.
